Hi guys,
2nd grow for me, this time I put the seeds directly into the soil, worked out fine, but one of the little ones is getting yellowish leaves. They are watered regularly, bot fertilised yet, the soil is not pre-fertilised.
looks like it is 3 weeks into flower, lol. that plant is a lost cause.
if there is no fertilizer in the substrate, you defnitely need to start fertilizing with a full, balanced diet. that should have started within the first week in a soilless context.
you need a well-balanced diet and you fertigate every irrigation with 10% runoff. this maintains the EC of substrate. Any nute-issues you see require a formula adjustment. buildup is impossible if religiously getting 10% runoff waste water.... doesn't mean you can't feed too much but the equilibrium that results in the substrate will be consistent after each fertigation. This is one of the primary benefits of soilless growing. consistency and knowing exactly what you are feeding.
Its toxicity. , soil was to rich for her. Light feeder. Water more, keep high humidity , give time, maybe she will make it through ...
If auto - i would start new seed, that plant wont grow big.
